Remote communities often grapple with challenges of distance from health care and support, but an outreach service for Aboriginal and Torres Strait Islander people in South Australia's Riverland is hoping to change this, with the help of a bus.

Bright and colourful, the Pi:Lu Bus is designed to be a safe place for Aboriginal and Torres Strait Islander people to receive help and health advice.

The bus is highly regarded and well recognised by Riverland locals, with a role of providing specific health prevention messages and free testing.

The mobile service is one of only a few in Australia.

"The bus is available to the Aboriginal and Torres Strait Islander community who may not be able to get into our service for reasons that they could not have transport available or their funds may be really low," Riverland Aboriginal Health Service coordinator Corinne Thompson said.

"I think the bus is helping to build relationships between our local Aboriginal people and some of our mainstream services as well.

"Any needs that the community have around their health, we're there to support them."
